I feel my friend is manipulating and bullying me. anyone with a knowledge of psychology got any advice for me?

In my opinion, I don't believe there is underlying manipulation here. He seems to be very frank with his emotions. What really needs to happen here is for you to set clear boundaries with him. You may need to sit down with him and discuss plainly what your intentions are for the future of your friendship if there is to be a future. I would advise you to contemplate what it is that you enjoy and dislike about the friendship, then decide how and when to proceed with your decision.
